We built this climbing backpack with the single-minded focus needed for one-day ascents on El Cap and dawn-to-dusk routes in the Bugaboos. It features an integrated, asymmetrical spindrift collar that opens wide and closes in a single motion for fast, hassle-free packing. This design eliminates excess fabric, ensures the pack stays open at hanging belays, yet protects your gear from nasty weather. Ergonomic shoulder straps match your torso’s contours for 24-hour comfort, and a removable webbing hip belt stays clear of your harness. Four rows of exterior daisy chains provide lashing options for a rope and helmet; adjustable ice tool loops allow a wide range of carrying options. Other details include an asymmetric profile for elbow clearance and a zippered vertical pocket on the lid for quick access to small essentials. Made from lightweight yet durable 6.25-oz 210-denier nylon double-ripstop and 6.05-oz 400-denier nylon ripstop treated with a polyurethane coating and a DWR (durable water repellent) finish; lined with a 1.8-oz 40-denier nylon double-ripstop with a polyurethane coating and silicone finish and 200-denier polyester.

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.
